Question

ALGUEM POR FAVOR ME AJUDE NESSA URGENTE com os polinômios f(×) =4×^5+8×^3+5×+2 g(×)=2×^5-3×^3+× e h(×)=7×^4-3×^3-9 determine A i(×)=f(×)-g(×) B j(×)= f(×)-h(×) C l(×)= g(×)-h(×)

Answer 1

Resposta:

Explicação passo-a-passo:

f(x)=4x⁵+8x³+5x+2

g(x)=2x⁵-3x³+x

h(x)=7x⁴-3x³-9

a)

i(x)=f(x)-g(x)=4x⁵+8x³+5x+2-(2x⁵-3x³+x)=4x⁵+8x³+5x+2-2x⁵+3x³-x=

  4x⁵+8x³+5x+2

 -2x⁵+3x³-x

_____________

  2x⁵11x³+4x+2

b)

j(x)=f(x)-h(x)=4x⁵+8x³+5x+2-(7x⁴-3x³-9)=4x⁵+8x³+5x+2-7x⁴+3x³+9=

   4x⁵+0x⁴+8x³+5x+2

         -7x⁴+3x³+0x+9

_________________

   4x⁵-7x⁴+11x³+5x+11

c)

l(x)=g(x)-h(x)=2x⁵-3x³+x-(7x⁴-3x³-9)=2x⁵-3x³+x-7x⁴+3x³+9=

  2x⁵+0x⁴-3x³+x

         -7x⁴+3x³+0x+9
